ABSTRACT:
A passive microwave receiver, receiving a WARC protected frequency of 1420 MHz may be used for fire, temperature speed detection and intrusion detection. One or more receiver arrays can be used to provide a plurality of frequency ranges that can be detected. In an interior installation, one or more receiver arrays can be placed inside a wall made of non-metallic substance and capable of passively receiving frequencies at less than 3 GHz. In other embodiments, the receiver and array can be in the form of a hand-held or wearable device. This method and apparatus achieves high performance by exploiting conventional low noise amplification block conversion circuits and provides the detection of thermal signals through clear, smoky, misty, or environmentally untenable conditions as well as the detection of automobiles and intruders via black box emission. A passive microwave detector may be used at a highway where the highway intersects an associated antenna lobe for a distance, mounted on a wall or pole and have line-of-sight view of an intruder or automobile.
